I came up with a way to get your 8 program switches using the Master Control unit.  I put an MV-65 Bank Select chip inside on a little perfboard.  Its a very simple layout.  The I attached 4 stereo jacks which each connect to the 4 dual remote switches (there are no LEDs, the hole is there because I used Molten MIDI 5 boxes to prototype it).

Each jack is for a pair of switches, so if you only want 4 presets per bank, then just use 2 remote switches.

The switches are program 1-8 going left to right.

Also, the 2 middle buttons on the Master Control are now Bank Down and Up.

The main advantages would be more flexibility in your pedalboard setup and that it can be built with off-the-shelf parts.

Let me know what you think of this approach:



If it's a winner, I will order right-angle cables rather than the straight ones in the photo.

What you need really depends on your goal.

If you want to keep it simple, use the MV-62 module and the 4 presets chip to recall 4 programs.

With the MV-62 module and 8 MV-57's, you can make something like this:

or if you only want to use 4 loops, you can make something like this:

You don't need to use all 9 switches on MV-62

With MV-58B Dev. Board and MV-65 Bank Select chip, you can make something similar to this but with tempo output:

Let me know if you have any questions.

I'm looking forward to seeing what you all come up with!

I just finished up an alternate version of the Master Control (MV-58B) as well as a separate control chip (MV-65) that sends Bank UP and DOWN and has 8 separate Program buttons with LEDs for selecting the 8 programs in each of the 16 banks.  When combined with the 9 switches module, a relay controlled pedalboard that stores and recalls 128 programs is an easy build.  You don't have to use all 8 switches, you wil just be limited int he total number of programs - 16 banks x number of program switches  = total programs

Check out the vid if you want to see it in action (it shows up about halfway through) and let me know what you think.  Thanks!
